A regasification optimization program was implemented at Montoir-de-Bretagne in 1984, and rapidly accepted by the operators. It has been an important tool for decision-making in the optimizing operation of this liquefied natural gas (LNG) storage and regasification terminal. The models used are regularly and easily updated on the basis of equipment behavior: aging or fouling. The Montoir-de-Bretagne LNG terminal is in the port area of Nates-Saint Nazaire on the Atlantic coast. It was commissioned in 1982 by Gaz de France. This terminal is used for receiving, storing, and regasifying the Algerian LNG received under a contract between Gaz de France and Sonatrach, as well as the LNG imported by Belgium and temporarily routed through France. It is designed to receive 25,000 to 200,000 cu m LNG carriers and has three 120,000 cm m LNG storage tanks. The daily sendout ranges between 6.7 million cu m and 36 million cu m. Monitor terminal supplies mainly Brittany and the Paris area. Two identifical berths allow the simultaneous reception of two LNG carriers. LNG is carried to the storage tanks in 32-in. lines at a rate of 12,000 cu m/hr. Each storage tank is equipped with three submerged 450 cu m/hr pumps with which the LNG is sent from the tanks to the secondary pumps at 8 bar. The nine high-pressure (HP) secondary pumps, with a capacity of either 450 cu m/hr or 180 cu m/hr, raise the LNG pressure to a level at least equal to pipeline pressure prior to revaporization.
